g vin g, su lho ent gauze top to said burner, a ring surrounding the burnergmcans to secure the ring on the burner and to retain the gauze top in place, integral arms on the ring, a shell supported on the arms above and surrounding the burner, said shell having an open base and perforations in its sides and top, and a cone supported in said shell and arranged with its point'extendin downwardly adjacent to the center of the ame.

4 In a gas heater, the combination with a gas burner, of a single shell arranged over the burner, having a substantially open bottom and a substantially closed top, and sides provided with a limited number of openings toward their upper portion, so as to retard the escape of the heat, said shell being entirely open and unobstructed in its interior v except for the cone, and an inverted cone of refractory material arranged in the shell with its apex adjacent to and above the burner, said cone being adapted to be superheated and retain the heat, promoting conibustion.

5. In a gas heater, the combination with a suitable standard, of a suitable burner having an enlarged burner portion, means for supplying mixed air and gas to the burner, a gauze top fitted to the enlarged burner portion, a ring of slightly larger diameter surrounding and extending upwardly above said burner portion and leaving a narrow annular space between it and said burner portion for the admission of alimited amount of air, integral lugs on the ring engaging with the gauze to set-screws on the ring engaging with the hurner, integral arms on the ring, a single interiorly open shell supported on said arms having an open base and perforations around its side and in its top, and an inverted cone of refractory material suspended on the shell and having its apex arranged adjacent to the burner.

6. In a gas heater, a suitable burner having in combination a central, tubular portion, a flaring portion at one end of said tubular portion forming an enlarged, open intakeend, a gas nozzle arranged adjacent to said open end to direct thegas thereinto, a flaring, enlarged burner portion at the opposite or outlet end of the tube, said burner portion being vertically arranged, a perforated cover forming a'ilat top to the burner portion, a ring of slightly larger diameter than the burner portion arranged around said portion so as to leave anannular space between them, said ring extending a short distance below the top of the burner portion and a short distance above said top, means to secure the ring on the burner, an inverted clay cone above the burner with its apex downwardly arranged to extend into the flame when burning, and a suitable support for the parts.

7. A gas heater composed of a suitable burner, a suitable support therefor, a ring of slightly'larger diameter than the burner arranged to surround and be supported on the burner, a single enlarged shell, having an open base and upper openings, supported 79 on the ring and arranged to extend around and over the burner, and an inverted cone s-upported'in the said shell and having its tip arranged adjacent to the upper portion of said ring.

8. In a gas heater, the combination with a suitable standard, of a suitable burner supported thereon having an enlarged burner portion, means for supplying mixed air and gas to the burner, a ring-of slightly'larger 80 diameter surrounding and extending upwardly above. said burner portion and leaving a narrow annular space between it and the burner port-ion, means to support the ring on the burner portion, a single, enlarged shell having an open base and perforations in its upper portion, means to support said shell on the ring, and an inverted cone of refractory material suspended in the shell and having its apex arranged adjacent 9a to the upper margin of said ring.

9. In a gas heater, the combination with a suitable standard, of a burner supported thereon having a smaller tubular portion and an enlarger burner portion, means for introducing air and gas into the burner tube at the opposite end from the burner portion, a ring of slightly larger diameter surrounding and extending abovesaid burner portion, means for detachably securing said ring on the burner portion, integral arms on the ring, and a single, enlarged shell having an open base and perforations in its upper portion supported on said arms and having its base arranged substantially on a level with the burner portion.

10. The combination in a gas heater, of a burner having a tubular portion provided with an open outer end and having an enlarged burner portion at its inner end, a perforated top on the inner end, a ring of slightly larger diameter than said inner end, clamped around thereto and extending above and below the perforated top, means to introduce gas mixed with air in the open end 5 and a suitable standard for the parts.

11. In a gas heater, the combination with a suitable standard, of a gas burner supported on the standard, a ring of slightly larger diameter than the burner supported 0 on the burner to leave an annular air space between theiring and the burner, a single shell supported above the burner to cover and inclose the burner, and a body of refractory material supported in the shell above 135,

and adjacent to the burner, said shell having openings in its sides and top.

12. In a gas heater, the combination with a suitable standard, of at-ubular burner supported thereon, said burner being bent at an 139 angle so that its inner portion is arranged substantially vertically and its outer portion substantially horizontally and having a flaring mouth at both its inner and outer ends, of a gas nozzle arranged adjacent to the outer mouth to direct the gas thereinto,

a perforated cap over said inner 'mouth, a metalllc shell slut-ably supported over sald inner mouth, and a body of refractory material supported in the shell immediately in above said inner mouth and adjacentthereto.

In testimony whereof, I have hereunto signed my name.
